LIQUID MIXER Filed Jan. 17, 1929 Patented July l, 1930 STATESr PATENT OFFICE l'ilOBEB'VI.` M. BAGLEY, OF HADDONFIELD, NEW JERSEY, ASSIGNOR T0 THE R. M. HOL- LINGSHEAD CO., A CORPORATION OF NEW JERSEY LIQUID MIXER Application mea January 17, 1929. seri'ai No. 333,089.

My invention relates to a new and useful soap mixer and it relates more particularly to a soap mixing device adapted for producing a stream of soap solution of suitable concentration by automatically drawing into a moving stream of water a suitable proportion of a concentrated soap solution so that a stream ot' soap solution of suitable desired vconcentration may be discharged from the apparatus.

My invention further relates to a novel soap mixer which is adapted to be attached directly to a water supply line and to be inserted into a suitable container, such as a steel drum or the like, containing a soap paste, that is, a semi-fluid soap, whereby said soap paste may be first thoroughly liquefied or reduced to a concentrated soap solution by the automatic addition of a suitable proportion of Water and whereby said llquefied soap or concentrated soap solution may then be automatically drawn into the moving stream of water in suitable proportion so as to convert the entire stream of water intoa corresponding stream of soap solution of suitable and desired concentration.

lVith the above ends in view, my invention consists of a novel construction including a base panel having mounted thereon a liquid.

jet vacuum pump of the Venturi type, to one end of which a water supply line may be attaehed.

My invention further consists in a novel combination of the liquid 'jet Vacuum pump mounted on said base panel, a soap intake conduit extending from said vacuum device within proximity of the bottom of the soap reservoir or drum and having a suitable control valve therein and a water supply conduit also having -a control valve therein communieating with the main water supply line in advance ot said vacuum device and extending within proximity of the terminal of the soap intake conduit.

For the purpose of illustrating my invention I have shown in the accompanying drawings forms thereof which are at present preferred by me, since the same have been found in practice to give satisfactory and reliable although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of the instrumentalities as herein shown and described.

In carrying out my invention I utilize any standard container 1 for storing the soap paste. This soap container 1 may be, and preferably is, the original steel drum in which the soap paste is shipped and supplied so as to save unnecessary handling or re-storing of the soap paste. The standard steel drum 1 is normally provided at its top 2 with a 3, onto which the base or panel 4 of my novel soap mixer is adapted to be mounted an'd secured. Thus` upon the removal of the usual cover from the top opening 3 of the drum,the panel 4 ot my device is mounted in place of said cover and serves again to close the drum. `V`A series of bolts 5 may be employed for rigidly securing the panel4 to the top 2 of the drum.

The panel 4 is provided at its bottom with an annular rib or projection 6 which fits into the opening 3 s as'to align'the panel with said opening. A pair of diametrically opposed upright standards or brackets' and 8 are provided on top of the panel 4, either secured thereto or formed integrally therewith.

Each of the upright standards 7 and 8 terminates in horizontal tubular supports 9 and 10, respectively. Within the tubular support IO the water supply pipe 11 is mounted, having at its receivingend any suitable valve 12, to the other side of which any suitable pipe or hose 13 may be attached for connection with the water main or supply.

llv means ot' the T connection 14 a graduated control valve 15 is connected to the water supply pipe 11 and to the lower end of the control valve 15 the water supply pipe 16 f is connected. The pipe 16 extends through a suitable opening 17 in the panel 4 and extends downwardly within proximity of the bottom 18 of the drum 1 where it preferably terminates in a cap 19 having a suitable number of small perforations i'or more uniformly distributing the water in the mass of soap paste 20.

The main water supply pipe 11 terminates in a nozzle 21 within the vacuum pump device 22, in operative juxtaposition to the constriction 23 in the main body\24. The discharge end 25 of the body 24 of the vacuum pump is threaded into the tubular bushing 9 on top of the upright bracket 7. The intake 26 is provided in proximity to the nozzle 21. The graduated control valve 27 is connected onto `he vacuum intake 26 and to the other end of the valve 27 the soap intake pipe 28 is secured. The soap intake valve 28 projects from a suitable opening 29 in the panel or closure member 4 and extends down within proximity of the bottom 18 of the drum. The soap intake pipe 28 also preferably terminates in a suitably perforated cap 30 to act as a strainer for preventing any semi-solid lumps of soap paste being drawn into the pipe 28. The auxiliary water supply pipe 16 and the soap intake pipe 28 terminate at the bottom of the drum or tank 1 in close proximity to each other. The pipes 16 and 28 may be secured to each other by a suitable brace or yoke 31 for maintaining their lower terminals in fixed relation to each other.

The jet of water issuing from the nozzle 21 and passing through the constriction 23 in the direction of the arrow 32 creates suction within the intake 26 and the pipe 28 so as to draw soap solution through said pipe and intake into the main stream of water. The soap solution thus produced is discharged through the pipe 33 and U-shaped trap 34 and the horizontal pipe 35 and the Vertical plpe 36 terminating in a strainer head 37.

The strainer head 37 is somewhat enlarged at the bottom and is provided with `.a transverse screen 38 retained in the bottom thereot by means of an expanding wire ring 39 seated in a suitable internal annular groove 5 40 within said strainer head. The screen 38 prevents the discharge of any solid or semisolid lumps of undissolved soap. A suitable hook 41 is preferably formed integral with the strainer head 37 and provides a support for the bucket 42 or the like, into which the soap solution is discharged for ultimate use.

The control valves 15 and 27 are preferably of the plug type, provided with handles 43 and 44, respectively, and suitable stop proj ections 45 and indicator dials 46 for gauging the amount of water admitted to the bottom of the mass of soap paste and for gauging the amount of soap solution drawn into the main water stream.

The U-shaped trap 34 serves to seal the discharge end of the vacuum device 22 withV a body of liquid so as to insure the instant operation of said device at any time. In operating my novel soap mixer the same is merely mounted upon any standard drum containing a soft soap or soap paste 20. It is merely necessary to force the two pipes 16 and 28 down throughthe mass of soap and then to clamp or secure the head or panel 4 over the opening in the top ot the drum. This may be effected by the series of bolts 5. The soap mixer thus mounted upon a drum remains there until the soap in the drum has been entirely consumed when the soap mixer is removed from the drum and again mounted onto a full drum of soap.

After having mounted the soap mixer on a drum of soap the main shut-off valve 12 is opened so as to admit a supply of water through the mixer. Vith the control valves 15 and 27 both closed, the supply of water admitted through the main shut-off valve 12 will be discharged through the strainer head 37 in its original condition.

In order to produce the desired soap solution, a lsuitable small stream of auxiliary water supply is admitted through the valve 15, and pipe 16 into the bottom of the soap mass 20. in proximitv to the terminal 30 of the soap intake pipe 28. This auxiliary water supply liquefies the soft soap or soap paste' so as to form a concentrated soap solution which may be drawn into the pipe 28 by the suction created within the vacuum device By opening the valve 27 to a suitable extent, a desired amount of the concentrated soap solution`is drawn into the stream of water passing through the vacuum device 22 vso as to produce a soap solution of suitable and desired concentration.

In Figure 7 I have illustrated a slightly modified form of construction embodying my invention, whereby the valve 27 shown in Figures 1 and 2 is replaced by a valve 47, also preferably' of the plug type having a main port 48 for connecting the pipe 28 with the intake 26 of the vacuum device 22 and having also an auxiliary port 49 in the plug thereof for connecting two stationary ports 50 and 51 in the body of said valve. The

auxiliary Water supply pipe 52 is connected to the stationary port 5() and the pipe 16 is then connected to the other stationary port 5l through a pipe 5?, and the needle control valve 54. By this means the auxiliary Water supply to the pipe 16 is automatically shut oli' whenever the soap intake is shut oli', so that the drum may not be accidentally liooded with water through the auxiliary Water supply line. The needle Control valve 54, or a valve similar to the valve'15, serves to control the amount of water admitted into the tank for liquet'yiug the soap.

l am aware that the inventionmay be embodied in other speciic forms Without departing from the spirit or essential attributes thereof, and I therefore desire the present embodiment to he considered in all respects as illustrative and not restrictive, reference being had to the appended claims rather than to the foregoing description to indicate the scope of the invention.
